Specicatioii of Letters Patent.

Patented June 5, 1917.

yApplication f1ed October 28, 191%. Serial No. 363,938.

To all 'whom t may concern:

Be 't known that I, Fnosil V. Simpson, a citizen of the United States,and resident of Milwaukee, in the county of Milwaukee and State ot'Wisconsin, have invented new and useful Improvements inPlaten-Connections, of which the following is a description,referencebeing had to the ac companying drawings, which are a part ofthis specification.

This invention has for its object to provide a rocking platen connectionfor box presses and the like such as the press tor clamping the liaps ofa paper or liber box shown in my co-pending application for LettersPatent Serial No. 847,819 filed J une 29th, 1914, which will permitofthe platen rocking in any direction to adapt itself to anunev'enthickness in theliber board and assure an even pressure throughoutthesura faces of the box blankwhichnare being glued together.

A box press of this character having a rigidly mounted platen may beincapable of applying suflicient pressure to the glued flaps at one'endof the box. if the flaps at the other end of the box a e thicker and toequalize the pressure against all of the seal-- ing flaps of the boxwhen ythe stock from which the box is made is of uneven thick# nesstheplatenunder the present invention is so mounted as 'to be capable oftilting to one side or the other or to` thev front or rear.

With the above and other objects in view the invention consists in theplaten connee tion as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters ofreference indicate the same parts in dierent views.:

Figure 1 is an end elevation of a press for clamping the flaps of paperor fiber boxes having a platen connection constructed in accordance withthis invention;

Fig-2 is an enlarged detailed sectional. side view of the platenconnection with the platenjn a horizontal position;

Fig. 3 is a similar' view with the platen tilted to the rear; l

Fig. 4 is a similar view with the platen tilted to the front; and

Fig. 5 is a similar view with the platen tilted to the left.

In these drawings the press is shown as co'n'lprising a verticallyTmovable plunger 14C slidably mounted ony a stationary support 11 andoperated by a suitable cam lever 17 and coperating with a platen' 2lcarried on the upper end ot a swinging platen stem '23 all vas describedin the application referred to.

The present lnvention has relation to the particular means for fasteningthe platen 24; to the u i er end ci the swing-ino' stem 23.

The upper end of the tubular ste-m23 is reduced 1n diameter so as tohave ample play within the socket 3G on the bottom of'.

the metal platen 24. A. thumb screw 31 is threaded through the socket 30and has a reduced end 32 to loosely 'lit within one 'of a number olopenings 33 formed in such reduced end of the stein 28 according to the.

mitted by' the play of the end of the thumb screw 'in the opening 33. y

By means of this platen connection the platen while retaining anapproximately ixed position on the swinging stem. is capable oit aslight inoiff'einent in any direction to adapt itself to a variation inthickness of the liber box liaps when such box 28 is placed thereon withits bottom forming aps treated with an adhesive folded together `uponthe platen and the plunger M is moved downwardly by the action of thecam lever 17. Thus an 'eren pressure is brought `to bear upon the liapsof the box notwithstanding a diderence in thickness thereof so that whenthe press is opened after the adhesive has set all aps will1zie-securely glued together.

The platen stem 2.3 is shown 'mounted in the socket 22 andl thisstructure is pivoted upon the pin Bil. This pin vcarried in the foot orhase plate 35 upon which the whole device stands. The socket 22 has arearw ardly extending bracket 36 carrying an adjusting screw, and alsohas a forwardly 23 yand the sockft 22 are swung elookwlse -about `thepin 34 until the toe 3S engages the base plate 35. In this position theplaens 24C and let` aredisalined andthe box with its one end sealed maybe removed and another which it is desiredto seal put in its place.

Thereupon the stem 23 is swung contraclockwise to again aline theplunger so that the box llaps which have been provided with paste may besealed together.

What I claim as new anldesire to secure i by Letters Patent is:

V1. A press for sealing flaps of paper boxesl pand the -like having asuitably operated of the socket and loosely entering an opening near theend of the stem to permit the platen to tilt` and adapt itself to avariation -in thickness of the material operatedupon.

2. A press for sealing flaps of paper boxes and the like, comprising asuitably operated plunger, a pivotally mounted socket, a platen stemadjustably threaded in the socket,- a platen opposed to the plunger andprovided with a socket loosely mounted on. the end of the platen stem,there being openings in the platen stem near the end thereof, and athumb screw platen and engaging one or another of the openings of theplaten stem according to the threaded adjustment of the platen stem andpermitting the platen to tilt in any direction to accommodate itself toa variation in thickness of the box aps. f

3. A .device for sealing the flaps of fiber boxes andthe like,comprising two platens, means for moving said platens into and out ofparallel alined relation, yielding'means for moving said platens towardeach other when alined, and a universal mounting for one of said platensso that pressures may be substantially equally exerted throughout thearea of said platens.

In testimony whereof, I affix my signature, in presence of twovWitnesses.
